So that seemed to work running against a validator 
I haven’t check Azure Api Management yet, because I now get a new issue which I assume has more to do with going from 6.0.2 => 6.0.3.
System.NotSupportedException: UserAuthRepositoryAsyncWrapper does not implement IManageApiKeys
at ServiceStack.ApiKeyAuthProviderExtensions.AssertManageApiKeysAsync(ServiceStackHost appHost, IRequest req) in /home/runner/work/ServiceStack/ServiceStack/ServiceStack/src/ServiceStack/Auth/ApiKeyAuthProvider.cs:line 548
at ServiceStack.Auth.ApiKeyAuthProvider.Register(IAppHost appHost, AuthFeature feature) in /home/runner/work/ServiceStack/ServiceStack/ServiceStack/src/ServiceStack/Auth/ApiKeyAuthProvider.cs:line 369
and
